Method Detail

match

public static MapResult match(com.hp.hpl.jena.sparql.expr.Expr expression,
                              com.hp.hpl.jena.sparql.expr.Expr pattern,
                              MapAction mapAction,
                              MapCallout mapCallout,
                              MapResult mapResult)

Match an expression against a pattern. If the pattern has variables in it, these are checked, by name, in the MapAction and the registered action invoked to determine whether the variable matches; if the pattern has a named funcion, the MapCallout is used to find a registered operation. Return a map of results, recording the bindings of variables
